Agreed.
I used to be a machinist, decades ago now, but I still have a milling machine,
a couple of metal lathes, and various other metal working tools.
I also worked as a welder, and have torches and a mig welder, but I only worked
with carbon steels.
Even better, I have access to people who are more skilled than I am at all of
the above.
I live in what was once a booming industrial town.
Anyway I think I have figured out a way to approach it. One way might be to
join the existing pieces with rivets. I will post pictures of the problem, and
the eventual fix when a solution is found.
Maybe Stu will allow them on the Photo Album site.
Stay tuned.

Do you have any way to take the parts to a machinist? I'm fascinated by the
things a good machinist can do and the problems they can solve.

I just got off the phone with the Edson factory, and while they did take a
look for me, it was to no avail.
According to the person I talked to, they have been cleaning house every
couple of years, and getting rid of the replacement parts that are not selling.
Taking up too much valuable space to keep all of it. So that was that.
Anyway, I have found out a few things that may be of some help to others.
The cable in this application is of particularly large diameter because the
clutch lever on the Yanmar "YSE, YSB, and YSM" series of one cylinder engines
requires a lot of force to actuate. He said that Edson does not stock anything
at all for cables that size any more. The ends have a 5/16 - 24 thread. From
grabbing the lever by hand, free of the cable, it is about all I can do to work
it. Got to be around 40 pounds. It is not difficult from friction, it is a
spring force that must be overcome to toggle it. My cable is getting stiff too,
but this must be why it was so big to start with.
I have found exact replacements for the cable from a few sources.
Some part numbers are as follows:
Morse D37912-4 120 IN, this is the one in the boat, series D37912, 4 inches
of travel, 120 inches overall length. Baum hydraulics can make up a cable with
the same core and characteristics. They are an industrial supplier, and the
industrial side of the Morse/Teleflex cable business was separated from
Teleflex marine products in the course of a few recent ownership changes
involving private equity firms. Teleflex now operates as "SeaStar Solutions",
still in British Colombia, at least for now.
The same size cable, but with a lower friction core construction, is the
Teleflex Extreme (TFXtreme) series 6400CC or CCX643xx which is the part number
pattern, where "xx" is the length in feet. Depends on the supplier which number
they are using. You have to make sure to be careful with the part numbers (also
CC695xx is the same from yet another supplier), as there are similar ones with
bulkhead instead of clamp fittings on one end. The Teleflex cable sounds
preferable, at a cost of $247 Canadian here in Ontario, or US$ 147 plus
shipping etc. from GO2 Marine in the Eastern U.S. This is for a 10 foot cable
of the same diameter and fitting requirements as what is in the boat now.

http://www.baumhydraulics.com/files/infobuild/morse_clamp_and_clamp_push_pull_cables.pdf
It might just be possible to install a clutch lever in the side of the
cockpit, and run a solid rod or tubular linkage to the clutch lever. The cost
would be about the same if the geometry works. Will probably try to patch the
existing part at least temporarily, but it is pretty clear that it won't last
without at least replacing the cable. Like everything else, there are trade
offs.

Steve,
When I worked at Edson several years ago there was a few cable clamps
left in inventory. You will need to call Edson direct on Tuesday to get one
since this part has been discontinued for decades. Replace your cable at the
same time because the reason the cable clamp broke was trying to hold a stiff
rusty cable in place. If you don't replace the cable, you'll simply break the
new clamp soon after installation. Edson also has a service bulletin on this
control assembly (model 747 IIRC)they can send to you electronically.

That is it, although the part in question is not visible in those
photos.
I have been able to draw the cable and associated parts out through the
top, but I am still trying to figure out what to do next.
It is not hard to imagine any number of ways to make a clamp, but to
make one which will be strong enough to do the job and also fit back in the
tube presents a real challenge.
I see no obvious way to improve on the original part, and the original
being made of stamped stainless steel, it will not be easy to duplicate or
repair.

Does your setup look like this?

If so the part I think you are referring to I have not been able to
locate.
I have considered making a spare, a project that hasn't got to the top
of the todo list yet.

My 1978 C&C27 has the type of shifter and throttle cable assembly
that is external to the Edson pedistal, and mounted on a pair of 1 inch
stainless tubes.
Yesterday the cable clamp on the shifter cable broke (under a lift
bridge, enroute to a race start...) and I have not been able to find any
reference this particlar part anywhere.
For the cable itself there are sources, but that does not help with
this particular problem.
The clamp has already been welded once, but to try that again would
require it to be welded in situ, which is tricky at best, given the fact that
it is thin stainless steel and immediately adjascent to the plastic parts of
the cable. I have a lot of respect for the welding skill of whoever did the
original repair.
The part consists of stamped sheet metal, formed so that it fits
into the annular detent on the shift cable and wraps around the cable. The ends
of the sheet metal strap have right angle tabs that interleave to form an
overall "D" shape, with a round head machine screw threaded through the flat
surface into a flat stainless steel bar and into the annular detent on the
cable. The bar extends up about 8 inches and is similarly fastened by a screw
through the casting at the top. The whole thing: cable, strap, and clamp, is
stuffed down inside the 1 inch stainless tubing when assembled.
If anyone else has been down this road, I sure would like to hear
how you handled it.
A source for the part would be great.
I have had no luck with online searches so far.
